 Team uses a cellulosic biofuels byproduct to increase ethanol yield Champaign IL (SPX) Oct 11, 2013 - Scientists report in Nature Communications that they have engineered yeast to consume acetic acid, a previously unwanted byproduct of the process of converting plant leaves, stems and other tissues into biofuels. The innovation increases ethanol yield from lignocellulosic sources by about 10 percent. Lignocellulose is the fibrous material that makes up the structural tissues of plants. It ... more |  |
Working together: bacteria join forces to produce electricity Tempe AZ (SPX) Oct 11, 2013 - Bacterial cells use an impressive range of strategies to grow, develop and sustain themselves. Despite their tiny size, these specialized machines interact with one another in intricate ways. In new research conducted at Arizona State University's Biodesign Institute, Jonathan Badalamenti, Cesar Torres and Rosa Krajmalnik-Brown explore the relationships of two important bacterial forms, de ... more |  |
Metabolically engineered E. coli producing phenol Daejeon, South Korea (SPX) Oct 11, 2013 - Many chemicals we use in everyday life are derived from fossil resources. Due to the increasing concerns on the use of fossil resources, there has been much interest in producing chemicals from renewable resources through biotechnology. Phenol is an important commodity chemical, and is a starting material for the production of numerous industrial chemicals and polymers, including bisphenol ... more |  |
Solving ethanol's corrosion problem may help speed the biofuel to market Houston, TX (SPX) Oct 03, 2013 - If we're to meet a goal set by the U.S. Environmental Protection Agency's Renewable Fuels Standard to use 36 billion gallons per year of biofuels-mostly ethanol-the nation must expand its infrastructure for transporting and storing ethanol. Currently, ethanol is transported via trucks, trains, and barges. For the large volumes required in the future, transportation by pipeline is considered to b ... more |  |
KAIST announced a novel technology to produce gasoline by a metabolically engineered microorganism Daejeon, South Korea (SPX) Oct 03, 2013 - For many decades, we have been relying on fossil resources to produce liquid fuels such as gasoline, diesel, and many industrial and consumer chemicals for daily use. However, increasing strains on natural resources as well as environmental issues including global warming have triggered a strong interest in developing sustainable ways to obtain fuels and chemicals. Gasoline, the petroleum- ... more |  |

UCLA engineers develop new metabolic pathway to more efficiently convert sugars into biofuels Los Angeles CA (SPX) Oct 03, 2013 - UCLA chemical engineering researchers have created a new synthetic metabolic pathway for breaking down glucose that could lead to a 50 percent increase in the production of biofuels. The new pathway is intended to replace the natural metabolic pathway known as glycolysis, a series of chemical reactions that nearly all organisms use to convert sugars into the molecular precursors that cells ... more |  |
First look at complete sorghum genome may usher in new uses for food and fuel Urbana IL (SPX) Sep 25, 2013 - Although sorghum lines underwent adaptation to be grown in temperate climates decades ago, a University of Illinois researcher said he and his team have completed the first comprehensive genomic analysis of the molecular changes behind that adaptation. Patrick Brown, an assistant professor in plant breeding and genetics, said having a complete characterization of the locations (loci) affec ... more |  |
First steps towards achieving better and cheaper biodiesel Bilbao, Spain (SPX) Sep 25, 2013 - Is there any connection between wine and biodiesel? The answer is yes, however surprising it may seem. Acetals are chemical compounds found in many wines, like port, for example, which give it a unique, sweet smell. However if acetals are blended with biodiesel, they improve its properties. The SUPREN research group of the Department of Chemical Engineering and the Environment of the Facul ... more |  |
Duckweed as a cost-competitive raw material for biofuel Washington DC (SPX) Sep 24, 2013 - The latest episode in the American Chemical Society's (ACS') award-winning Global Challenges/Chemistry Solutions podcast series describes how the search for a less-expensive, sustainable source of biomass, or plant material, for producing gasoline, diesel and jet fuel has led scientists to duckweed, that fast-growing floating plant that turns ponds and lakes green. Based on a report by Christodoulos A. Floudas, Ph.D., in the ACS journal Industrial and Engineering Chemistry Research, the new podcast is available without charge at iTunes. ... more |  |
Algae Biofuel Can Cut CO2 Emissions by up to 68 Percent Compared to Petrol Minneapolis MN (SPX) Sep 20, 2013 - Algae-derived biofuel can reduce life cycle CO2 emissions by 50 to 70 percent compared to petroleum fuels, and is approaching a similar Energy Return on Investment (EROI) as conventional petroleum according to a new peer-reviewed paper published in Bioresource Technology. The study, which is the first to analyze real-world data from an existing algae-to-energy demonstration scale farm, sho ... more |  |
Stanford scientists use 'wired microbes' to generate electricity from sewage Stanford CA (SPX) Sep 20, 2013 - Engineers at Stanford University have devised a new way to generate electricity from sewage using naturally-occurring "wired microbes" as mini power plants, producing electricity as they digest plant and animal waste. In a paper published today in the Proceedings of the National Academy of Sciences, co-authors Yi Cui, a materials scientist, Craig Criddle, an environmental engineer, and Xin ... more |  |
